Alberto Salazar was last night blasted by the athlete he accused of lying over doping allegations made against him.

Kara Goucher ripped into Mo Farah's coach, said she stood by every word and offered to repeat them under oath.

She further alleged that individuals had been threatened at the US trials, where she is competing, and claimed “multiple sources” have come forward since the BBC Panorama show accusing Salazar aired.

Asked what her message would be for any athlete thinking about teaming up with Salazar, she said: “Think long and hard because you're going to be labelled something for the rest of your life.”

Goucher added: “I want my son to be able to believe in the sport and the system. I want USADA (US Anti-Doping Agency) to show they work and I want justice for everyone involved.

“My love for the sport is much greater than what people think about me. People think I'm a liar, a manipulator. That sucks. But I care more about the future of the sport. I knew it would be ugly, it hurt a lot more than I thought it would but, hey, I'm human.”

Goucher spoke out days after Salazar came out fighting in an attempt to clear his name – and 48 hours after Farah decided to stick with the man who turned him into a double Olympic and world champion.

“I'm not going to comment on Mo and (training partner) Galen (Rupp),” she said. “They have their truth and they have their reasons. I'm not around them. I can't imagine what they're going through. My experience is my experience. I can only share that.

“I get constantly, all day long, people passing me information and wanting me to bring it forward.

"I really want to encourage all the people that have reached out to me to reach out to USADA to please come forward. The case is much stronger if it comes from you.”

Goucher revealed that she agreed to testify after watching Lance Armstrong confess all to Oprah Winfrey.

“I saw Lance Armstrong on Oprah, then after Oprah Travis Tygart (chief executive of USADA) was on,” she said. “I told (husband) Adam, 'you get me that guy and I'll talk to him'. Seven days later I was in his office talking to him.

“I encourage everybody to come forward, share what they know and do what's right for the sport. This is bigger than us. This is bigger than me.

"If my career ended tomorrow I'd still be fighting this fight because I care what happens in the future. I feel very passionate about it.”
